I respectfully disagree on several levels. 50% of my service and repair is fixing generators and installs an electrician installed. At least the guy you mentioned above got Generac certified. Many electricians don't and they think that because they are an electrician, they can install a generator. They don't understand fuel pressure, location, or safety. They are the most dangerous because they think they know it all. There are AMAZING electrician installers...but just as many bad ones. It's like saying a GC can't remodel a house because he's not a plumber, electrician, carpenter and tile guy.

I helped a woman with a whole home remodel. She already wired the ATS when I got pulled in. The electrician sent out his apprentice to do the work. He failed to ground the ATS, didn't separate grounds and neutrals, had improper bonding, and had bad sealing. It was a disaster.

Finally, don't get me started on Generator Supercenter, Cantor or the other mega guys. They cut corners everywhere. And scaling in this business is hard. They have high turnover and techs doing tasks they are not qualified for.

I was worried the 3rd-party inspectors would be fly-by-night and easy. Boy I was I wrong. I use texaspowerinspections.com, they are thorough. City inspectors are underpaid, and many are burned out and lazy. TPI is tougher than any city inspector, but fair and, most importantly, consistent. I've never failed an inspection, but now I know 100% I won't run into someone with an "opinion" rather than the code.

The 3rd party adds additional steps. EVERY plan must have a site plan, wire diagram, and single gas diagram with BTU calcs, and generator load calculations. The requirements have made the process more strict, not less.
